Type:Cylindrical Roller Bearings  

Material: Bearing Steel

Cylindrical roller bearings, the rolling element is a radial rolling bearing with cylindrical rollers. Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling body and the retaining edge of the ring is small, which is suitable for high-speed rotation. According to whether the ring has ribs, it can be divided into NU, NJ, N, and other single-row bearings and NU, NN and other double-row bearings. The rollers and the raceway are in line contact or repaired offline contact. To withstand heavy loads and shock loads. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing. The N type and No. type can move axially, can adapt to the change of the relative position of the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support
Note: N type bearings are bearings without ribs on the outer ring (that is, the outer ring has no axial restriction on the rollers), while bearings of type N are bearings without ribs on the inner ring (that is, the inner ring has no axial restriction on the rollers).
